TECHNICAL FIELD

The present disclosure relates to the technical field ofMachine-to-Machine/Man (M2M) communication, and in particular to anintelligent method and an intelligent system based on an M2M system.

BACKGROUND

An M2M communication network, which extends the communication categoryand communication field of present information communication networks,acquires information from the physical world by embedding intelligenceand communication capabilities into various possible objects, andenhances and improves the intelligence, interactivity and automationdegree of the services of the present information communication networksbased on the analysis and processing on the information.

The M2M communication network have various network forms, which might bean independent physical network built separately, or might be a logicalnetwork built on present public communication networks and variousgovernment/enterprise private networks.

The M2M communication network can be divided into three layerslogically, including: a perceptive extension layer, a network/servicelayer and an application layer.

The perceptive extension layer mainly implements the acquisition,automatic identification and intelligent control of physical worldinformation. Each object itself in the physical world has nocommunication capacity. Intelligent nodes, such as a sensor, anactuator, an intelligent device, a Radio Frequency Identification (RFID)reader-writer and the like, acquire the information of the physicalworld and interact the information with the network layer through acommunication module. An M2M terminal device is divided into two types,one of which is an M2M terminal capable of communicating with an M2Mcommunication network and the other is an M2M gateway capable ofcommunicating with an M2M communication network and an M2M stub network.

The network/service layer supports the transfer, routing and control ofinformation from the perceptive extension layer, and provides a basisfor the communication between man and object, between object and objectin the Internet of Things. According to the classification of theInternet of Things, the network layer specifically includes networkforms such as a communication network, Internet, an industry network andso on; the main component of this layer is an M2M platform.

The application layer contains various specific applications of theInternet of Things, including both public service and industry service,in which the industry service might be a public industry serviceorientating the public or might be a private industry service meetingthe requirement of special applications in an industry, and the publicservice is a basic service provided in view of the universal need of thepublic, such as intelligent home, mobile payment and the like. Theprivate industry service generally is provided for the inside of theindustry in view of the particular requirement of the industry, forexample, smart grid, intelligent transportation system, smartenvironment and so on. Part of industry services also might bepublic-orientated services, for example, an intelligent transportationsystem, which is called an industry public service. The main componentcontained in the application layer is an M2M application.

Terminal peripheral refers to a single device having an environmentsensing function, such as a sensor, which can transmit the sensedinformation to an M2M service platform or M2M application through an M2Mgateway or M2M terminal, and meanwhile can receive the downlink controlby the M2M application or M2M service platform.

An electronic guiding system shows the sceneries in a scenic spot andthe exhibits in an exhibition hall to tourists in the form of voice,image, text and so on, so as to spread the connotation of the sceneriesand exhibits and bring out a more vivid effect while the tourists arewatching the sceneries and exhibits; therefore, tourists can obtain agood knowledge while enjoying the experience of the sceneries andexhibits.

If the electronic guiding system and the M2M system can be combined, theelectronic guiding function implemented based on a strong M2M systemwill bring a great convenience to users and will provide more richguiding services to users. However, there has been no solution tocombine an electronic guiding system and an M2M system in related art sofar.
